JAMES F. LEWALLEN, OF NIGHOLASVILLE, KENTUCKY.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 245,521, dated August9, 1881.

Application filed June 11, 1881. (No model.)

To all whom it may concern:

Be it known that I, JAMEs F. LEWALLEN, acitizen of the United States,resident of Nicholasville, in the county of Jessamine and State ofKentucky, haveinvented a new and valuable Improvement in Gar-Couplers;and I do hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a longitudinal section of the device. Fig. 2is a perspective view, parts being broken away. Fig. 3 is an enlargeddetail section. Figs. 4 and 5 are details.

This invention relates to improvements in car-couplings; and it consistsin the construction and novel arrangement of parts, as hereinafter setforth.

In the annexed drawings, the letters a a represent the .draft-timbers ofa car, connected at their front ends by cross-beams b b, and in rear ofthese by a block, 0, and brace d. The brace is connected to the upperedges of the timbers, and has on its lower front corner a The block 0 islocated in front of but below this brace, and has in its top the angularnotch f. Aligned with this notch in the top of cross-beam b is formedanother notch, g. Seated in these notches is the draw-bar h, having itstail k beveled on top at 70, and provided with a transverse stop or key,I, in rear of block 0. This key prevents the draw-bar from being drawnout too far by traction, and in front of block 0 the draw-bar isprovided with a shoulder, l, which prevents said draw-bar from beingdriven in too far by buffing.

Attached to brace d is a spring, m, arranged lengthwise of and bearingupon the draw-bar h, holding the latter in place.

If a car should jump the track, the pressure would force the spring upand allow the drawbar to slip from its notches, separating from the car,and avoiding the derailment thereof. The beveled surface eand curved top70 materially assist this action, for as the rear of the draw-bar risesthe pressure on the bevel guides it forward, preventing the key fromfalling behind the block 0 and holding the draw-bar.

Inside the draw-head is formed an elongated seat, a, which opens at theshoulders 10 into a link-chamber, q; Back of these shoulders the seatdrops, forming a stop, 1', and the recess is deeper in rear of saidstop. In this deeper portion is placeda spring, 8, which bears againstthe rear of a pin-supporting block, 75. At the rear end this block hasthe depending heel t, which fits in the deeper portion of the seat, andin front the block is grooved transversely at a, forming a short underlip, u, and a longer upper lip, a. This block is thrust forward by theaction of the spring, the heel bearing against the stop 1, and the pin'0 supported on the front end. The incoming link x drives the block fromunder the pin, allowing the latter to fall into the said link.- The linkis caught in the groove a, and held closely againstthe pin, ready toenter the opposite draw-head.

. In the mouth of the draw-head are placed the link-guide springs to,which are attached in front and extend rearward obliquely, and not onlyconduct the link centrally, but give a yielding pressure in traveling.

What I claim, and desire to secure by Letters Patent, is-

The combination, with a draw-bar arranged in open or notch seats f g,and having the transverse stop or key I, of the longitudinal spring m,bearing on the upper surface of said drawbar, substantially asspecified.

In testimony that 1 claim the above I have hereunto subscribed my namein the presence of two Witnesses.

JAMES F. LEWALLEN.
